Cannot reinstall NIS after running NIS Beta

I installed Norton Internet Security Beta for Windows 10. It uninstalled my NIS for Win 7. Now, I cannot get the Beta to renew (14 days to check it over? C'mon, get real.) nor can I get the previous version to install again. I keep getting the error there are no installs left. I thought when I bought it I had three installs and I only used two. What now? Running naked on the net is not a good feeling.
